问题描述

在计划的网络维护窗口期间，会生成多个警报，指示 LDAP 和 Netlogon 服务器无法访问。

观察到以下 EMS 消息：

<nodename>: secd.ldap.noServers [EMERGENCY]  Node: <nodename>  Time: Aug <Date and time> -0400  Severity: EMERGENCY   Message: secd.ldap.noServers: None of the LDAP servers configured for Vserver (<svm name>) are currently accessible via the network for LDAP service type (Service: LDAP (NIS & Name Mapping), Operation: GetUserInfoFromId).  Description: This message occurs when none of the configured Lightweight Directory Access Protocol (LDAP) servers are accepting connections.   Corrective Action: From an LDAP client workstation, make sure that all configured LDAP servers are responding to requests. Ensure that there are no networking issues stopping the cluster from communicating with the configured LDAP servers. Also, ensure that the portmapper running on the LDAP server is working correctly.   Source: secd  Sequence#: 2574539 []
